Recently I heard that the content of an Iphone is stored in encrypted form meaning that if I were to take apart the Iphone and managed to extract the memory and read it, I wouldn't be able to get any information out of it.
I find this hard to believe because an Iphone can be unlocked and opened in a mater of seconds, the decryption of 16 gigabytes of data in that short a time seems too fast to me. I would like to know what is happening exactly.
Is the memory not actually encrypted, is decryption actually just that fast or is there something else happening.
Just to be clear, my impression was that when you unlock the phone (not just when you turn it on initially) everything is decrypted. obviously turning on the phone provides more than just a few seconds of time to decrypt the phones content.
Additionally, I would be interested not only in Iphone encryption but also the encryption of Androids and other smart phones.
